The predator's path
If you go north from Wekesa’s position (have to walk quite a bit), there are some bouncing mushrooms that can take you to the higher ground. Then go south you will reach the next objective.
I am stuck where I have to speak with Wekesa, there seems to be no way out only a closed door… Bug or someone figured it out?
Yeah, I found that misleading as well.
Nothing more complicated than that you haven’t realised that you’re done with the instance for now. If you’re like me, you’re staring at the green star, which is well within the instance zone, and feeling convinced that you need to get to it (and indeed, when in doubt that’s what I normally do, and check that it really says “Exit to Tyria” before I leave). But on this occasion there’s genuinely no path to it – and if you check at bottom-right you’ve got the familiar “Leave instance” icon. Time to go back to the larger world and run, therefore.
(Sorry – this was a bump of an old post – but having become stuck at the same point myself, it seemed worthwhile answering it.)
